About

This is a multicenter, randomized, sham-controlled, patient- and assessor-blinded, and parallel trial to explore the effectiveness and safety of electroacupuncture (EA) therapy, compared with sham EA, for poststroke shoulder pain.

Full description

This study is aimed at showing the effectiveness and safety of electroacupuncture therapy for the stroke survivors with shoulder pain. 60 stroke survivors with shoulder pain will be enrolled in two traditional Korean medicine hospitals and randomly divided into either of verum or sham electroacupuncture group with 1:1 of allocation ratio. The participants will receive 9 sessions of electroacupuncture procedures for 3 weeks. Patients and outcome assessors will be blinded from the beginning to the study completion. Visual analogue scale will be primarily evaluated, and pain rating scale, Fugl-Meyer assessment upper extremity, modified Ashworth scale, manual muscle test, passive range of motion, Korean version of modified Barthel index, and Korean version of Beck depression inventory will be measured, too. Blinding index will be assessed. For safety, adverse events will be collected.

Enrollment: 45 patients

Sex: All

Ages: 19+ years old

Volunteers: No Healthy Volunteers
